Description (last modified by warmerdam)

(Gdal doesn't calculate stats correctly if the image is GDT_Byte with PIXELTYPE=SIGNEDINT. In gcore\gdalrasterband.cpp, function ::GDALRasterBand::ComputeStatistics(…) 

                switch( poBlock->GetDataType() )
                {
                  case GDT_Byte:
                    dfValue = ((GByte *) poBlock->GetDataRef())[iOffset];
                    break;
